    Temporal Variation in Polynesian Fishing Strategies: The Southern Cook Islands in Regional Prespective

    Get PDF
    Geographic variability in Polynesian fishhook assemblages has long been recognized but largely unexplained. West Polynesian assemblages are typically small in number, relatively uniform in morphology, and often manufactured from Turbo. Those from East Polynesia are comparatively large and morphologically varied, and Pinctada margaritifera is the preferred raw material. Drawing on both geographically dispersed assemblages and the temporal sequence from Aitutaki, Cook Islands, I suggest that these assemblage differences stem from both structural properties of the two shell species and their differential availability through time and across the region. I also examine two sets of selective conditions, one that initially led to an increase in the frequency of angling in East Polynesia and a second that subsequently fostered a decline in angling on Aitutaki and possibly elsewhere in the region.

    Mass Capture Fishing in the Marquesas Islands

    Mass capture of small fishes with a variety of nets, traps, and weirs was widely practiced and economically important across East Polynesia at western contact. Archaeological research, however, has suggested these technologies were less important during the early settlement period and gained prominence over time. Several explanations have been proposed, including resource depression, changes in marine environments, and/or social and economic reorientations. In the Marquesas Islands, pelagic and offshore fishes were historically well represented in early assemblages relative to most Polynesian islands. Here we report on fishbone assemblages from Nuku Hiva Island that were recovered with fine mesh screens, identified using a wide range of skeletal elements, and analysed with morphometric methods. The Hakaea Beach results demonstrate that mass capture of small fishes was especially important at this locality and sustained over three early, successive occupations. These patterns may reflect the nature of the local fisheries, preferential use of high-return capture strategies in this reef-limited setting, and/or purposeful avoidance of ciguatera-prone fishes and a preference for less vulnerable fishes. Overall, our findings highlight geographic variation in early Marquesan fisheries and provide archaeological evidence that mass capture technologies had an important place in the maritime toolkits of the earliest East Polynesian fishers

    Employer-Provided Retirement Planning Programs

    As older workers approach the end of their working career, they face a series of important decisions that will determine their economic wellbeing during their remaining lifetime. They must decide when to retire, when to start Social Security and company pensions, whether to annuitize 401(k) balances, and whether to take lump sums from defined benefit plans. Lack of knowledge or insufficient financial literacy may lead to regrettable decisions. This chapter assesses employer provided financial education as well as pre-retirement planning programs and examines their effectiveness in increasing knowledge and altering retirement behavior

    Pension Plan Distributions: The Importance of Financial Literacy

    Get PDF
    This chapter examines workers’ plans to take lump sum distributions versus life annuities from employer retirement plans. The analysis is based on before and after surveys of retirement eligible workers who attended employer-provided retirement planning seminars. We consider workers’ planned distributional choices from both defined benefit and 401(k) plans. A minority of respondents plan to take the non-default options, highlighting the importance of framing. Additionally, higher financial literacy is associated with lower rates of annuitization in both plans. We explore how participants change their planned distribution choices after attending seminars that enhance financial knowledge and understanding of retirement plans

    Volunteer Income Tax Assistance (VITA) Program Dramatically Increases Knowledge Retention And Student Skills

    Get PDF
    In academia, faculty have the challenge of developing programs that will instill in the students the core competencies and skills defined by the accounting profession as the benchmark for successful entry into the accounting profession by college graduates. By integrating participation in the Volunteer Income Tax Assistance program with the teaching of concepts in the classroom at Utah Valley State College, faculty have been able to increase the retention of knowledge and the development of practical skills that benefit students, potential employers, and the community

    v. ill. 23 cm.QuarterlyHuman colonists of Remote Oceania readily took advantage of the naive virgin fauna encountered on previously uninhabited islands, a bounty that was quickly depleted. Subsequent developments in Polynesian subsistence economies were more subtle, varied, and complex. These features are illustrated in a comparison of two quite different subsistence archives from the postcolonization period: archaeofaunal assemblages and stable isotope (d13C and d15N) records of humans, pigs, and dogs from the same archaeological contexts. The samples come from four stratified sites, with a total of 22 distinct occupational strata that represent a 600-year period on the small (18.4 km2) almost-atoll of Aitutaki in the southern Cook Islands. Benefits and challenges of integrating these quite different records are considered in the context of specific findings, with implications for subsistence studies elsewhere. In particular, differences in formation processes, taxonomic resolution, and contrasting spatial and temporal scales represented by each record are highlighted. A complex, multiscalar picture of subsistence change emerges, showing variability within and across the three species and the two subsistence archives. Findings support prior interpretations that established (not colonial) settlements are represented by the currently known Aitutaki archaeological record. Within the relatively stable and largely anthropogenic food web, humans occupy a central position throughout the sequence. Through time, a reduction in fishing and decreased consumption of marine carnivores is indicated; these changes are likely to be an outcome of both repeated storm events and considerable shoreline disruption in the fourteenth century A.D., and cultural decisions about the relative costs and benefits of various fishing activities vis-a`-vis other subsistence needs. An apparent reduction in variability of pig diets in late prehistory could reflect interspecific competition between pigs and their human managers, although small sample sizes constrain interpretations. Overall, use of two quite different subsistence archives provides a more robust, but also more complex, view of subsistence change across individuals and communities on Aitutaki

    Detecting spatial regimes in ecosystems

    Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological potential (i.e. potential vegetation), and often fail to account for ongoing changes due to stressors such as land use change and climate change and their effects on plant and animal communities. We use Fisher information, an information theory-based method, on both terrestrial and aquatic animal data (U.S. Breeding Bird Survey and marine zooplankton) to identify ecological boundaries, and compare our results to traditional early warning indicators, conventional ecoregion maps and multivariate analyses such as nMDS and cluster analysis. We successfully detected spatial regimes and transitions in both terrestrial and aquatic systems using Fisher information. Furthermore, Fisher information provided explicit spatial information about community change that is absent from other multivariate approaches. Our results suggest that defining spatial regimes based on animal communities may better reflect ecological reality than do traditional ecoregion maps, especially in our current era of rapid and unpredictable ecological change

    Regime shifts and panarchies in regional scale social-ecological water systems

    In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate those interactions. The case studies show different ways that adaptive governance may be triggered, facilitated, or constrained by ecological and/or legal processes. The resilience assessments indicate that complex interactions among the governance and ecosystem components of these systems can produce different trajectories, which include patterns of (a) development and stabilization, (b) cycles of crisis and recovery, which includes lurches in adaptation and learning, and (3) periods of innovation, novelty, and transformation. Exploration of cross scale (Panarchy) interactions among levels and sectors of government and society illustrate that they may constrain development trajectories, but may also provide stability during crisis or innovation at smaller scales; create crises, but may also facilitate recovery; and constrain system transformation, but may also provide windows of opportunity in which transformation, and the resources to accomplish it, may occur. The framework is the starting point for our exploration of how law might play a role in enhancing the capacity of social-ecological systems to adapt to climate change

    Human settlement of East Polynesia earlier, incremental, and coincident with prolonged South Pacific drought

    The timing of human colonization of East Polynesia, a vast area lying between Hawai‘i, Rapa Nui, and New Zealand, is much debated and the underlying causes of this great migration have been enigmatic. Our study generates evidence for human dispersal into eastern Polynesia from islands to the west from around AD 900 and contemporaneous paleoclimate data from the likely source region. Lake cores from Atiu, Southern Cook Islands (SCIs) register evidence of pig and/or human occupation on a virgin landscape at this time, followed by changes in lake carbon around AD 1000 and significant anthropogenic disturbance from c. AD 1100. The broader paleoclimate context of these early voyages of exploration are derived from the Atiu lake core and complemented by additional lake cores from Samoa (directly west) and Vanuatu (southwest) and published hydroclimate proxies from the Society Islands (northeast) and Kiribati (north). Algal lipid and leaf wax biomarkers allow for comparisons of changing hydroclimate conditions across the region before, during, and after human arrival in the SCIs. The evidence indicates a prolonged drought in the likely western source region for these colonists, lasting c. 200 to 400 y, contemporaneous with the phasing of human dispersal into the Pacific. We propose that drying climate, coupled with documented social pressures and societal developments, instigated initial eastward exploration, resulting in SCI landfall(s) and return voyaging, with colonization a century or two later. This incremental settlement process likely involved the accumulation of critical maritime knowledge over several generations

    The assessment of vascular risk in men with erectile dysfunction: the role of the cardiologist and general physician.

    Erectile dysfunction (ED) and cardiovascular disease (CVD) share risk factors and frequently coexist, with endothelial dysfunction believed to be the pathophysiologic link. ED is common, affecting more than 70% of men with known CVD. In addition, clinical studies have demonstrated that ED in men with no known CVD often precedes a CVD event by 2-5 years. ED severity has been correlated with increasing plaque burden in patients with coronary artery disease. ED is an independent marker of increased CVD risk including all-cause and especially CVD mortality, particularly in men aged 30-60 years. Thus, ED identifies a window of opportunity for CVD risk mitigation. We recommend that a thorough history, physical exam (including visceral adiposity), assessment of ED severity and duration and evaluation including fasting plasma glucose, lipids, resting electrocardiogram, family history, lifestyle factors, serum creatinine (estimated glomerular filtration rate) and albumin:creatinine ratio, and determination of the presence or absence of the metabolic syndrome be performed to characterise cardiovascular risk in all men with ED. Assessment of testosterone levels should also be considered and biomarkers may help to further quantify risk, even though their roles in development of CVD have not been firmly established. Finally, we recommend that a question about ED be included in assessment of CVD risk in all men and be added to CVD risk assessment guidelines
